A ride includes a first device and a second device. The first device has an adjustment mechanism. The second device has an adjustment mechanism. Any one of the first device and the second device is a lighting device in which a direction of a light source of light is adjustable. An opening is formed in the ride. The adjustment mechanism of the first device and the adjustment of the second device can be operated by being accessed from outside through the same opening.

An example sensor bracket assembly can include one or more cold plates forming a core bracket structure, wherein the core bracket structure and the one or more cold plates provide structural support for the sensor bracket assembly; a housing enclosing the core bracket structure; one or more sensor mounts for mounting one or more sensors on the sensor bracket assembly; and one or more attachment portions for attaching the sensor bracket assembly to a body of a vehicle.

A holder (2) for fixing a sensor (1) to a motor vehicle includes a frame (7) and walls that bound an opening (8) for receiving and fixing the sensor. At at least two opposing walls (10, 11) each respectively have at least one clamping portion (14) for clamping the sensor (1) in place in the opening. At least two further opposing walls (12, 13) each respectively have at least one receiving portion (19, 20) for receiving a portion (6) of the sensor (1), wherein at least one of the receiving portions (19) has a spring portion (18) for pretensioning the sensor (1) toward the opposing wall (12).

A rhizome-growth monitoring device of a clonal plate is provided, including a supporting frame. A first adjustment rack is fixed above a side of the supporting frame, a side end of which is movably connected to a second adjustment rack. A connection sleeve is movably connected to a bottom end of the second adjustment rack. A lifting cylinder is fixed in the connection sleeve. A camera group is fixed to the lifting cylinder through a connection plate. A rhizome growth monitoring sleeve is fixed at a bottom end of the connection plate, and includes an outer sleeve, an inner sleeve, and a radar monitoring head. The outer sleeve is fixed onto the bottom end of the connection plate. The inner sleeve is screwed to an inner side of the outer sleeve. The radar monitoring head is installed in the inner sleeve and close to a bottom surface thereof.

A sensor assembly for a vehicle includes a base, a sensor body mounted to the base and rotatable relative to the base around an axis in a direction of rotation, and a cover. The sensor body includes a sensor window and a wall having heat fins elongated circumferentially relative to the axis. The cover is positioned to cover the heat fins. The cover includes an inlet open in the direction of rotation. The cover defines an airflow path from the inlet through the heat fins. The cover includes an outlet positioned to direct air across the sensor window.

Low-cost devices for measuring radar transmission and/or reflectance of coated articles are provided. An exemplary low-cost radar transmission and reflection measurement device includes a radar transmitter that emits a radar signal, a radar target to which the radar signal is directed, and a radar receiver that receives the radar signal. Further, the exemplary low-cost device includes a sample holder located between the radar transmitter and the radar target and between the radar target and the radar receiver. The sample holder receives a sample including a coating. The low-cost device also includes a controller connected to the radar transmitter and radar receiver. The controller measures a radar signal loss due to the coating.

A new kind of active protection system (APS) called SNAP (scalable networked active protection) will be a light and affordable means of protecting vehicles and infrastructure against rockets and missiles. The APS system is built from modules, each of which is itself a stand-alone APS. Since each unit is a stand-alone APS, the only single points of failure are the User Interface (UI) in the vehicle cab and the Data/Power Router (DPR). SNAP instead takes advantage of each module protecting a relatively small area to employ vastly lower cost components. In addition, each SNAP module is disposable in that when its countermunition is initiated, the entire module is consumed and subsequently replaced in the field. This approach allows the system to be very compact and lightweight.

Phased array antennas, such as a multi-function aperture, are limited in performance and reliability by traditional air-cooled thermal management systems. A fuel-cooled multi-function aperture passes engine fuel through channels within the ribs of the multi-function aperture to provide better heat transfer than can be achieved through air cooled systems. The increased heat transfer and thermal management results in a multi-function aperture with improved performance and reliability.

An apparatus for ground penetrating radar includes an antenna disposed within a sleeve. The sleeve includes a radar-absorbing material for attenuating the amplitude of incident radar waves. The sleeve has an aperture for permitting radar waves ω pass into and out of the sleeve. A method for surveying a formation using ground penetrating radar includes rotating the antenna and sleeve while keeping the antenna and sleeve longitudinally stationary, and recording data including the amplitude of waves received by the antenna and the position of the aperture when such waves are received.

The present disclosure is drawn to a device for improving the transmission behavior of radar waves, comprising a mounting section to which a radar sensor can be fastened, and a wall section having a first surface and a second surface, wherein radar waves that are emitted by the radar sensor, when fastened to the mounting section, impinge on the first surface by an angle of incidence α, β, γ, δ, enter the wall section, and leave the wall section via the second surface. The radar waves travel a traveling distance (d) between the first surface and the second surface, the first surface and the second surface being shaped such that the traveling distance (d) of the radar waves stays constant for every angle of incidence α, β, γ, δ.
